2024 ‘increasingly likely’ to be warmest on record: EU monitor

The Copernicus Climate Change Service (C3S) said last month was the second warmest on record books going back to 1940, only slightly cooler than July 2023.

Between June 2023 and June 2024, each month eclipsed its own temperature record for the time of year.

“The streak of record-breaking months has come to an end, but only by a whisker,” said Samantha Burgess, deputy director of C3S.

Last month the global average temperature was 16.91 degrees Celsius, only 0.04 C below July 2023, according to C3S’s monthly bulletin.

“The devastating effects of climate change started well before 2023 and will continue until global greenhouse gas emissions reach net zero,” she said.

From January to July global temperatures were 0.70 C above the 1991-2020 average.

This anomaly would need to drop significantly over the rest of this year for 2024 not to be hotter than 2023 — “making it increasingly likely that 2024 is going to be the warmest year on record,” said C3S.

‘Too hot to handle’

July 2024 was 1.48 C warmer than the estimated average temperatures for the month during the period 1850-1900, before the world started to rapidly burn fossil fuels.

This has translated into punishing heat for hundreds of millions of people.

The Earth experienced its two hottest days on record with global average temperatures at a virtual tie on July 22 and 23 reaching 17.6 C, C3S said.

The Mediterranean was gripped by a heatwave scientists said would have been “virtually impossible” without global warming as China and Japan sweated through their hottest July on record.

Record-breaking rainfall pummelled Pakistan, wildfires ravaged western U.S. states and Hurricane Beryl left a trail of destruction as it swept from the Caribbean to the southeast of the United States.

Temperatures for the oceans, which absorb 90% of the excess heat caused by human activities, were also the second warmest on record for the month of July.

Average sea surface temperatures were 20.88 C last month, only 0.01 C below July 2023.

This marked the end of a 15-month period of tumbling heat records for the oceans.

However, scientists at C3S noted that “air temperatures over the ocean remained unusually high over many regions” despite a swing from the El Nino weather pattern that helped fuel a spike in global temperatures to its opposite La Nina, which has a cooling effect.

On Wednesday, World Meteorological Organization Secretary-General Celeste Saulo reflected on a year of “widespread, intense and extended heatwaves”.

“This is becoming too hot to handle,” she said.
